inosine/hemorrhage

BACKGROUND Glutamine supplementation of total parenteral nutrition (TPN) in stressed patients has been advocated. To determine whether glutamine supplementation affects the host response to conditions of stress, animals were given TPN with or without glutamine for 7 days. They were then subjected to

BACKGROUND Hemorrhagic shock produces a marked decrease in hepatic ATP, adenylate energy charge, and total adenosine nucleotides. This is followed by slow recovery to normal levels after resuscitation. Nucleotide metabolites are increased following shock and resuscitation. Previous experimental work

BACKGROUND Substances that inhibit Na/K ATPase activity appear in plasma during severe septic shock causing Na and fluid to move into cells and K to move out, resulting in cell swelling and an elevation of plasma K. These changes contribute to the morbidity of sepsis. Recently, we reported that

BACKGROUND Hemorrhagic shock leads to the appearance of substances in plasma that depress Na/K ATPase activity leading to a rise in plasma potassium. Recently, we reported that adenosine can stimulate Na/K ATPase activity, lower the plasma potassium back to control and prolong survival in shocked

Inosine, a naturally occurring purine formed from the breakdown of adenosine, has recently been shown to exert powerful anti-inflammatory effects both in vivo and in vitro. This study evaluated inosine as a potential therapy for colitis. Colitis was induced in mice by the administration of dextran

Pyruvate improves cellular and organ function during hypoxia and ischemia and stabilizes the NADH redox state and cytosolic ATP phosphorylation potential. In this in vivo study, we evaluated the effects of intravenous pyruvate on cardiovascular and neocortical function, indexes of the cytosolic

An initial clinical phase I trial of inosine dialdehyde has been carried out in 40 patients at dose levels of 30-4000 mg/m2 for 5 days given intravenously (iv) monthly. At 1.5 g/m2, noncumulative dose-related toxicity occurred in all patients which consisted of nausea and vomiting, local pain,

BACKGROUND Pegylated interferon combined with ribavirin treatment is an effective therapy for chronic hepatitis C viral infection. However, pegylated interferon combined with ribavirin is associated with various adverse reactions. Severe thrombocytopenia is a life-threatening side effect of

Infectious pancreatic necrosis virus (IPNV) and viral hemorrhagic septicemia virus (VHSV) remain two of the most important pathogens of farmed trout worldwide. Mycophenolic acid (MPA) is an inhibitor of cellular inosine monophosphate dehydrogenase (IMPDH), an enzyme that catalyzes an essential step

The present study deals with the effects of immunomodulators on the morphology of intracerebral arterial walls in rabbits with experimental subarachnoid haemorrhage (SAH). Immunostimulators:thymostimuline and inosine dimethylamino-isopropanol-p-acetamido-benzoate were found to aggravate the

Gastric mucosal microcirculation and purine nucleotide metabolism were studied after hemorrhagic shock and retransfusion in rats. The number of perfused microvessels and the concentration of adenosine triphosphate, adenosine monophosphate, inosine monophosphate, inosine, hypoxanthine, xanthine, and

The effect of experimental anaemia induced by phlebotomy and the effect of infusion of various fluids on the 2,3-DPG, ATP and total organic phosphate (Porg) concentration were examined in the red cells of beagles made anaemic by withdrawal of 30% of the circulating blood. Particular groups of dogs

Pyruvate (PYR) improves cellular and organ function hypoxia and ischemia by stabilizing the reduced nicotinamide adenine dinucleotide redox state and cytosolic ATP phosphorylation potential. In this in vivo study, we evaluated the effects of intravenous pyruvate on neocortical function, indexes of

The cerebral cortical cup technique was used to monitor changes in adenosine and inosine levels in the rat cerebral cortex during periods of hypoxia, anoxia, or hemorrhagic hypotension. Basal levels of adenosine and inosine in cortical perfusates stabilized within 10 min at concentrations of 30-50
